Evaluate each log without a calculator
Mrac [35]

QUESTION 1

The given logarithmic expression is

\log_4(\frac{1}{16})

We rewrite \frac{1}{16} in the index form to base 4.

This implies that;

\log_4(\frac{1}{16})=\log_4(4^{-2})

We now apply the power rule: \log_a(m^n)=n\log_a(m^n).

\log_4(\frac{1}{16})=-2\log_4(4)

Recall that logarithm of the base is 1.

\log_4(\frac{1}{16})=-2(1)

\log_4(\frac{1}{16})=-2

QUESTION 2

The given logarithm is;

\log_2(\sqrt[5]{32})

\log_2(\sqrt[5]{2^5})

This is the same as;

\log_2(2^{5\times \frac{1}{5}})

\log_2(2^{1})

\log_2(2)=1

What equation has a slope of 2 and a y intercept of -5
DIA [1.3K]

Answer:

y=  2x - 5 equation has a slope of 2 and a y intercept of -5

Step-by-step explanation:

Given:

The slope  = 2

Intercept of y = -5

To Find:

The equation of the line = ?

Solution:

The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.

The equation of the line in the slope intercept form is

y = mx+b

where

m is the slope

b is the y intercept

Now substituting the given values we get

y  = (2)x  + (-5)

y=  2x - 5

A pre-paid cell phone plan has a flat rate of $15 with an additional cost of $0.15 per
Tresset [83]

Answer:

anything less than 133 would be true

Step-by-step explanation:

35 ≥ 0.15m + 15

solve for m

subtract 15 from both sides

20  ≥ 0.15m

divide both sides by 0.15

133.33  ≥ m

m cannot be more than 133 minutes

F(x) = 1/x^2 and g(x) = 1/2x+4<br><br> f[g(x)] = 4x 2 _____
Korolek [52]

Answer:

f[g(x)] = 4x²+1/16

Step-by-step explanation:

We need to put g(x) into f(x).

f[g(x)] = 1/(1/2x+4)²

f[g(x)] = 1/(1/4x²+16) Solve the exponential.

f[g(x)] = 1/(1/4x²+16) Simply the fraction.

f[g(x)] = 4x²+1/16
